Introduction to Duke of Destruction 3D- High-Resolution Reproduction Edition (1)

The biggest disaster in Los Angeles.

The first level is the Hollywood massacre.

First, get a magazine next to the wooden box, shoot and detonate the gas tank next to the vent, and fall to the ground along the blasted ventilation pipe. After landing, kill the tiger-headed paratroopers on the wooden box, then jump from the wooden box to the window and then to the high wall on the right. At this time, a rocket launcher will slowly rise. After getting the rocket launcher, enter the room through the second window. In the room, there is a monitoring screen, which can observe the main scene of this pass. Kill a tiger-headed paratrooper and get rockets and steroids (on it). Medical atoms on the windowsill can increase 50 health points. When taking medical atoms, two tiger-headed paratroopers will fly to attack you. Hurry back to the street and use the terrain to destroy them.

Attack the cinema ticket office with a rocket launcher and blow up a passage. Kill the tiger captain in the room next to the ticket office once, otherwise it will escape invisibly and suddenly attack from behind.

After turning on the light switch on the left side of the iron gate, open the door and enter the lounge of the cinema. There are several monsters lurking in the hall, so we should adopt the tactics of divide and conquer. The controller on the counter can open a secret door of a secret room, and a shotgun can be obtained in the next room. When you enter the bathroom, there is a big mirror inside. Don't hit the monster in the mirror. Toilet-relieving can increase 10 health points, with only one effect. If you break the urinal, a water column will come out. Press the space bar where there is a water column, and the health will increase to 100. There are shotgun bullets behind the bathroom sofa.

Break the vent with a gun and enter a secret room along the vent. After killing two tiger-headed paratroopers, open the secret door and enter the movie screening room. After some efforts, I got the blue card. However, when taking medical atoms from the projection room, a secret door will be opened, so be careful that the tiger-headed paratroopers will come out from it. Turn on the projection switch, the curtain below slowly opens, and the movie begins. There are several tiger-headed paratroopers shooting at you in the cinema. Go down and kill them. In the middle position of the actor on the screen, there is a broken sign. Note that there is such a sign in the game, suggesting that it can be blasted with weapons. Blow it up with a rocket launcher and get a jet pack in the room behind the screen. It can be used to enter the other three secret rooms (the cinema lounge, the neon lights at the entrance of the cinema, and the top floor of the cinema) to obtain bulletproof vests, three submachine guns, control bombs, jet packs, etc.

In the lounge, the video game room can be reached by elevator. Detonate the indoor gas tank with a gun and kill the monster. The game machine on the right can open a secret door to get Duke's body double. Here are some power sockets, and you will get an electric shock if you touch them. Open the iron gate with a blue card and enter the room. The opposite wall will explode when it approaches. Meet officer pig head here. The shotgun in its hand is very powerful, and it is often used sideways, which is more difficult to hit.

The second Red Light District.

At first, there were tiger-headed paratroopers outside, followed by patrol airships. Destroy them. If you are seriously injured, you can break the fire faucet in the street and fill your health at the water's edge. Enter the library, destroy the monsters inside, and pay attention to searching for various items and secret doors. Remote control bombs and incendiary bombs can be obtained in a secret door. There is an invisible switch on the left side of the mirror in the library and bathroom. You can get night vision goggles with one click. There is a rocket launcher in the darkroom with red curtains. Go back to the library counter, press two buttons in the middle of the four buttons respectively, and open the door lock. Destroy the monsters in the dark passage with night vision goggles, and then take the elevator upstairs. There are several tiger-headed paratroopers in the upstairs room. You can get three submachine guns and blue cards after killing them. Attention, you will meet a pig-headed policeman when you get off the elevator.

In the street, after a fierce battle, I went to the guard room of the building on the right, put in a blue card and a set of buttons rose from the console. Press all the buttons first, and then press the two buttons on the side to raise the blasting switch. Turn on the blasting switch and blow up the building opposite. Huang Ka can be found in the ruins of buildings.

Open the door with yellowcard, kill two pig-headed policemen who guard the door, and quietly touch and kill two tiger-headed paratroopers at the billiard table with a shotgun. Then you can play billiards with the space bar. There are some monsters in the bathroom next door. There is a dark tunnel behind the urinal on the left side of the bathroom mirror, which contains good and bad items.

Go back to the billiards room and take the first aisle on the right to the bar. After a bloody battle, you can replenish ammunition behind the counter. There are red cards in the secret door on the side of the counter against the wall. Enter the nightclub with a red card. The dancers here are also monsters. After the gunfight, you can break the vent on the right with a gun, stand on the table, jump in with a long jump and get a remote-controlled bomb, which can be used to kill several pig-headed policemen patrolling under the vent. After going out, turn on a switch opposite. At this time, the red curtain slowly opened and a frustum of a cone rose. Kill some new pig-headed policemen, see ghosts, and are about to fight. At this time, two iron gates descended back and forth. It turns out that this is a trap set by the pig-headed police.

The third floor is death row.

At first, he was tied to the electric chair by a monster, and he had to press the ↑ key quickly to get rid of it. Stand by the window and kick a pig-headed policeman to death in the guard room, and you can win a shotgun. Go to the closet in the guard room and get an automatic pistol. Kill an attacking pig-headed policeman, press the button on the left side of the guard room, lower the electrocution chair and get ammunition. Press the button on the right side of the guard room again, open the red curtain of the interrogation room, destroy the monster in the interrogation room and enter a church. Press a switch in the middle of the church altar, the light suddenly turns red, and a back passage appears behind the cross hole. Break the glass on the left, you can enter the back passage and get a three-tube submachine gun. The round button above the steps can be opened by shooting. This button can lift the elevator behind you to get medical atoms and armor.

After leaving the church, there was something in the iron gate on the left. Walking on, the wall on the right suddenly exploded with a gap, which contained two large rotating gears. Jump into the left room with equipment as a springboard and get a blue card and a rocket launcher. A medical atom and night vision goggles can also be obtained at the edge of the wall next to the gear. Open the door of the main passage with a blue card. The enemies here are mainly pig-headed policemen. They used lasers to block thunder, minefields. First kill the pig-headed police officer who is guarding the door, blast the first minefield with a rocket launcher, and rush into the bathroom to get protective boots. Come out from the bathroom to the opposite room, skip the laser beam at the door, get the shotgun bullet next to yellowcard, and translate it towards the exit to get yellowcard. At this time, the laser has been excited to stop the thunder, so I rushed to the door and rushed out with a long jump. Then I faced two pig-headed policemen.

Go down into the hall, open the exit door, destroy two monsters and get the rocket. The enemy has a lot of firepower here, and there are two airships and four automatic laser cannons. Don't continue to fight, and run to the left as soon as you get out. After getting the red card by the wall, hurry back to the hall.

Open the door on the left side of the hall with a red card, press the switch to open the revolving door after going up, then turn around and press a switch on the outer wall to quickly return to the inner floor of the room. When the revolving room rises to the second floor. Through the mezzanine aisle, two doors open separately. There are switches on both sides of the bathroom to open the ion doors of channels 1 and 2. You can see a huge submarine on the monitor screen in yellowcard's room, which is the exit of this customs. Destroy the monsters in rooms 1 and 2 respectively, and obtain ammunition and articles. Take the room as a cover, destroy the automatic laser guns on the opposite platform one by one with rocket launchers, and shoot down the patrol airship with three submachine guns. Note that there is a picture in the last room of aisle 2. I rushed in and found that this was a secret passage. Walking along the passage, I finally saw the submarine, but the monsters near the submarine also jumped wildly.

After killing the monster, open the gate by the rock and get the submersible at the door. Jump from the doorpost on the other side of the gate to the platform and take a lot of things. There are two secret passages here.

Go back to the water and go in from the bottom of the submarine, and you can see the bottom of the submarine. There are two monsters ready to sneak attack. There is a secret door behind the wooden box.

The fourth toxic waste dump (toxic dump)

This pass is mostly played underwater, so we should pay attention to saving weapons. At first, dive into the water, press the up and down buttons of three buttons vertically placed on the wall of the diving pipe, and then a door next to it opens. After going out, you will see a submersible in the water in the first underwater area. In addition, there is a hole in the underwater rock wall. Destroy several alien monsters in the cave, blast the tunnel and go straight to get some remote-controlled bombs. After coming out of the water, use a remote-controlled bomb to blast the hole wall behind the waste bucket and reach a new place.

As soon as it appeared, it encountered a fierce exchange of fire. After destroying the monster, take out a rocket launcher and a blue card from the small hole next to the diving pipe and open the door with the blue card. After entering, pay attention to the secret door on the right wall, kill two monsters, blow up the laser mines laid by the monsters and get submachine gun bullets.

Go out to the garbage disposal plant, stand at the end of the conveyor belt, let the mechanical claw lift it twice and put it on another conveyor belt. Quickly break the glass on the right door and rush in to kill a pig-headed policeman, get a red card and open the door leading to the corridor. There is a monitoring screen here, where you can observe the situation everywhere. Then go back to the conveyor belt and come to the reaction room, destroy a few pig-headed policemen and flip the switch. There are several medical atoms in the reaction chamber, which can increase the health to 200. Keep walking, and you will return to the end of the conveyor belt.

Go right, and a secret door will open behind you. After killing a few pig-headed policemen, you will find another submersible on the slope of the secret door. Turn on the switch with a red card, revealing a reduced gun. After shooting, the gun becomes smaller. At this time, you should run fast, go in through the square hole on the right, and then turn right quickly until you rush into another room. Because the time to become a villain is limited, you should run all the way, otherwise the game will be over as soon as it is big. After destroying the two monsters in the room, press the switch to open the door to another underwater world. Then run back, don't turn left this time.

When diving into the water again, there are mines everywhere, and hordes of monsters send out psychological shock waves from time to time. Press the switch in the underwater control room and the whole rock will float up. When you surface, you will meet several monsters. After the fierce fighting, I came to a high-rise rock, jumped into the opposite platform in a long jump and entered another control room. Press a convex switch in the control room to open an underwater gate, and don't press another concave switch to get a rocket launcher. You may find a crack in the rock next to it. When it is shelled, it will open a secret passage. Go out along the secret passage and find that you have returned to the original place. If your submersible is running out, you can go down to the grass to get a new submersible. Then return to the original road, dive into the water again, enter the newly opened underwater gate, and launch an underwater war with the embattled alien monster. Press the switch of the third underwater control room to open another underwater channel. After opening the door, return to the second underwater area. If the submersible consumes too much, you can go ashore and get a second submersible on the slope.

Then enter the underwater gate, destroy several alien monsters and come to a new place. There are two rotating gears blocking your way. Take advantage of the gap between the broken teeth of the gear and insert it quickly, otherwise the game will end again. When I finally escaped from the gear gap, the damn alien monster was ahead again. After a fierce battle, the submersible was exhausted and resurfaced. At this time, I will fight with several tiger paratroopers.

Walking along the waterway, a secret passage can be blasted on the right wall and it will fall into a large water reservoir. There are also a group of alien monsters in the reservoir. Don't fight recklessly, come to the surface quickly. After landing, destroy the monster in the control room, turn on a switch, open an iron gate opposite, then come down from the control room, stand on the rock and clean up the underwater alien monster with a remote-controlled bomb.

After the threat is lifted, go upstream, climb the steps on the right and stand on the black iron shelf (there is also a back passage on it). When you shoot the round switch in the opposite iron gate with a gun, the iron frame under your feet will move to the center. Jump quickly to another iron shelf so that you can reach another step.

There are several medical atoms in the vent, which can increase health to 200. When entering the sewer near Guandi, the left wall can blast the passage to the secret passage.

Secret launch facility (launch facility)

This is a secret passage, which enters from the bottom of the fourth passage. First, turn on the switch behind the big turntable. Then kill the monster on the road and enter the round room. Follow the plank road on the wall of the room, all the way into the central control room, get the blue card and press the switch. After going downstairs, go in through the 1 gate, and scuffle with a group of tiger-headed paratroopers in another room. After winning, open gate 2 from the inside. There is a passage to main control room in the scuffle room just now. Put a blue card in the main control room and you can see a launch vehicle rising slowly from the launch pad.

Move on, destroy a few pig-headed policemen on a guard platform, get a red card and open the door of the launch pad. There is an elevator on the left side of the launch pad, which can enter the middle of the launch pad. There is a transfer point that can be sent to the launch vehicle. After entering the rocket, put the red card into the device and then exit the original way. In the underground bunker on the left, two pig-headed policemen were killed. When the switch in the local fort was pressed, only a loud explosion was heard, and the launch vehicles of alien monsters were blown up one by one. Then get off the elevator on the right and go to the basement. There are several medical atoms behind the basement. After killing several tiger captains and alien monsters, open the door and enter the sewer leading to the fifth level.

Abyss (abyss)

Turn right after coming out of the sewer, kill two tiger-headed paratroopers and get protective boots. Then jump into the river and get the blue card from the mountain road on the left. There will be many monster attacks along the way, and it is best to deal with them with three submachine guns.

Use the blue card to open the iron gate under the place where you got the protective boots. You can use the long jump on the back steps to jump into the middle cave. The cave is connected with the cableway and leads to the bunker at the top of the mountain. You can take something by the bunker, but you can't get in.

After retreating from the original road, move on and jump to another step with a long jump. This is a tombstone. When I walked to the tombstone, the earthquake suddenly started. Looking down from the edge of the cliff, there seems to be a cracked hole under the high rock. After many twists and turns, I entered the cave and it was very dark. I can only see the situation in the cave with night vision goggles. Destroy several tiger-headed paratroopers in the first hole. Continue to go up, kill two alien monsters and come to a dry well. Throw some remote-controlled bombs down there. Looking down, the monster has been killed, leaving only a fire burning. After getting goods and weapons around the dry well, they walked to the fire and were transported to the bunker. Destroy several monsters in the bunker and get some items. Return from the fire. Press a manual switch, open the stone gate, enter a castle along the corridor, press the manual switch below the castle, and raise a circle of stone ladders. Go up the stone stairs and press the manual switch on the small step next to the cross hole. An elevator rises behind you and there is an explosion in the opposite rock. You should quickly board the ascending elevator, press another manual switch, and let the narrowing gun on the opposite rock hit you through the horizontal hole of the castle. When you become a villain, jump off the elevator and go out from the small hole under the castle.

Here, you can clearly see a big hole in the opposite volcanic rock, which is the nest of alien monsters. Jump off the rock, wade through the hot magma, come to the road leading to the hole, climb up from the rock on the right, and reach the cave with iron gate. Along the way, there were many monsters, many secret passages, and many articles and ammunition. Go straight ahead and enter the monster's lair.

This cave is very long, and it will go all the way to a shaft. You can dive with a jet backpack, and you can get bullets and shells at the shaft wall and the bottom of the well. When you open the round door and meet an alien general, you can go up quietly from the left, don't cross the ditch, and don't take ammunition by the ditch. When the alien general walks back and forth, fire a rocket launcher at him and knock him down. The alien monster's nest on the earth was destroyed, and the Duke of Destruction received an urgent telegram from the lunar base.

The Second Apocalypse of the Moon (Apocalypse of the Moon)

The first clear space station (Spaceport)

On the earth space station, enemy ships attack from time to time outside the window. The enemy encountered in this level has reinforced aliens, who are quick in action and fierce in firepower, and can also cast poison gas. At the beginning, I took a step back, put it on the spaceship and got rocket launchers and steroids. There is a secret door in the middle of the control room, where the ion door switch is turned on. There are blue cards in the basement of the ground floor, and some items and weapons are in secret doors and passages. Open the console next to the hall with a blue card and open the elevator door to go upstairs. When you get to the next level, kill all the monsters. When you get the spray bag, turn on the pneumatic switch on the small floor opposite the elevator. At this time, a set of buttons appeared in the central control room. Press the second button and the third button to open the ion column in the center of the hall. Jump off the ion column and get a red card in the water. There are weapons and objects on the ion column.

Press the space bar near the red key lock to open the channel.

The second incubator (incubator)

If you keep going, you will be attacked by the guard bees of the alien legion. Most of the monsters at this level lurk in the dark, so pay attention to the monsters nearby when pulling the switch or opening the door. The place marked CDF is the phantom wall. Enter the ion gate and destroy the brain-sucking monster inside. First, take the yellowcard from the down passage on the left, then tap the round switch in the right room, open the iron gate of the left passage and enter the reservoir. There are many monsters and weapons in pools and caves. In addition, there is a switch on the hillside that can open the door to the bottom.

Third-order warping coefficient

When coming out of the teleport point, be careful of the left and right attack of two guard bees. Go to the middle room to get weapons and articles first. Watch out for the attack of security bees here, and then take the elevator on the left to get the blue card in the crack. Take the elevator on the right, open the door with the blue card, enter the space passage and take it to Huang Ka. After opening another door, go back the same way. Kill an alien general in front of the yellow gate, bring the conveyor belt up and open the ion door leading to the bottom in the rotunda.

The fourth melting station (Fusion Station)

There are many monsters along the way. Before the oblique crack in the rock, two automatic laser guns at the entrance of the opposite power system building were knocked out by rocket launchers. At the bottom of the power system building, kill the latent enhanced aliens first, and then enter the reaction room from the side of the monitoring screen. Because the pipeline in the reaction room is too narrow to pass through, you can open the manual switch at the other end of the pipeline by shooting and open the elevator door leading to the hydropower generation area. There is a phantom wall at the upper right of the elevator door. The secret passage behind the wall can reach the place where you just couldn't get in and get two medical atoms. After going up, pull two switches underwater and open the elevator door leading to the atomic energy generation area. At the exit of the power system, the floating boat can be controlled to move to the opposite entrance by shooting the round switch. After fierce fighting, I broke through the circular passage. You can reach the Red Room by shooting the opposite manual switch. There is a time limit for opening the exit of the Red Pavilion, so you should rush out quickly after pulling the switch. In front is the room leading to the bottom, and you can only fly by jet pack. After passing, you'd better land by the door. After the door is opened, destroy the UFO aliens who use rockets from the inside. The devil rises slowly from the ground, and passes through the customs after destroying the devil.

Level 5 occupied territory (occupied territory)

Fight all kinds of monsters in the same way, and it is best to let the enemies kill each other. After coming out of the Red Chamber, enter the main battlefield. First, in the cave with brain-sucking eggs, take the conveyor belt, get the red card and get the destruction gun, then come down and open the door of the blue card room. Destroy two very fierce alien generals in this room and come to the bottom of the rotating holographic monster's head through a narrow passage. There is a square switch on the wall behind him. After being shot, a green bottom leading to the first secret checkpoint will appear on the opposite wall.

The rotation period of the secret first level.

This is a huge cyclotron gravitational field, which is located in the outer layer and the inner layer of the cyclotron gravitational field respectively with the monster. There are many weapons and ammunition in the room on the outer floor, and there is also a switch to open the first door on the opposite inner floor. Because of the gravitational field, monsters can't reach the outer layer except guarding bees. You can use rocket launchers to attack monsters from a distance, kill a large number of living enemies, and then fly over to clean up the remaining enemies. Turn on the switches in all the inner rooms and enter the core of the gravitational field. After killing the core alien general, enter the sixth level.

Tiberius station on the sixth floor

I met a mirror as soon as I entered the door. Don't hit it. The monster comes out from the right. Go up from the elevator on the left and get a blue card in the central control room. After entering the blue gate, destroy a group of guard bees. This is another mirror. You can get a red card under the water where alien monsters haunt. Destroy an alien general in the Red Gate. The door leading to the bottom can't be opened from the front, and you have to go through the vent behind the crater fire to enter the bottom.

The seventh Lunar Reactor (Lunar Reactor)

Turn left in the cross hall and get a blue card in the bathroom. Then enter the blue gate, come to the cliff from the astronaut dormitory on the right, fly to the opposite tunnel entrance with a jetpack on your back, and take it to yellowcard. After rushing forward at the crack in the rock, quickly retreat into the hole. At this time, there was a big explosion in the tunnel and a new passage was blown up on the right. Go up the channel and cross the poisonous river. Finally, you can get a red card in the room. On the way back, take the stairs on the left, open the door with a red card and return to the Cross Hall. After entering the Yellow Gate, destroy an alien general. There is a charge restorer in the upper control room to restore health. After the lower door is opened, be careful that a large number of enhanced aliens and frisbee aliens lurk in the dark. There will be a big explosion in the passage to Guandi, so we should pay attention to avoid it in time.

The eighth floor is the dark side.

Enter the T-corridor, get the armor on the ground, the freezing gun and the medical atoms in the secret room, open the iron gate on the left, and take the tram to a cave to get the blue card. Go back to the T-corridor, go through the blue door and take the tram to another cave on the upper floor to get the yellowcard. When you return to the T-corridor, open the yellow door.

In the circular square of the Observatory, a tiger-headed paratrooper on the opposite wall was killed with a rocket launcher before the guard bees appeared. At this time, when a group of guard bees come at you from the high-altitude observation room, they can run along the circular square, keep a certain distance from the guard bees, and then destroy them one by one with three submachine guns.

In the valley next to the square, an alien general and several reinforced aliens lie in ambush. After a bloody battle, they came to a cave. The wind echoed in the cave and there was a strange stone tablet. The stone tablet used to be a teleportation point. Entering from the front will meet many alien monsters. You'd better not photograph this woman hanging on the wall. The bottom of this passage is in the well at the end of the cave.

Secret secondary, extremist.

Walk around the fence and destroy the monsters outside. Tap four switches to open the door of the central building. There are three special-shaped generals and a group of reinforced special-shaped tiger-headed paratroopers. Finally, press the manual switch on the wall inside the building to open the door to the ground floor. When you become a villain, you can quickly pass through the passage and enter the ninth level.

Level 9 Alien Demon (Overload)

You can get a medical atom by turning on the manual switch underwater. Come out of the water, kill the monsters around you, and turn on the four switches under the two paintings. Press the manual switch by the door, go in and shoot an alien general, kill it and come to the incubator of the brain sucker. There is a hole sealed by a circular iron plate on the left side of the corner on the second floor of the incubator. After blasting, it was found that ion waves blocked the way. Continue to the third floor, there is a switch behind a woman hanging upside down in the opposite corner, which can turn off the ion waves that are in the way.

From the hole where I have just been, there is a huge fan blade spinning. After obtaining medical atoms, I jumped down from the gap of the fan blade. I saw the rotunda filled with brain-sucking eggs and detonators. I hit the detonator, destroyed the brain-sucking monster, blasted the passage to the pool, and killed two alien monsters in the pool by the way. Guandi's alien demon king is very powerful. He wants to jump into the pool next to the hall and storm the alien lich king with three submachine guns and destruction machine guns.

Three-level flowering bomb city (shrapnel city)

First pass raw meat (raw meat)

First take the destruction machine gun from the secret room on the right side of the tall building and kill an enhanced alien. Then, jump into the pool from upstairs to avoid injury. Watch out for sharks and alien monsters in the pool. When climbing a hill, you can get medical atoms and remote-controlled bombs by climbing over the fence on the right, blasting corners, diving into the water, passing through caves and floating to another surface. After entering the Japanese restaurant, the table at the second rice collapse place will automatically sink, revealing a tunnel. When you go in and press the switch, you can open a secret room with many monsters. Enter this secret room, destroy the monster and get the blue card. Open the blue door and find some pig-headed policemen singing karaoke in the room on the left. After killing the monster, you can sing a song in front of the microphone. There is a passage under the kitchen sink, from which you can get a red card. When you open the red door and reach the top of the slope, it will cause an earthquake. Behind the flame in the depression after the earthquake is the bottom.

Second Customs Bank (Bank List)

No sooner had I jumped off the wall than I got into a fight with a group of monsters. In the opposite room, a patrol airship came out. After going upstairs from the elevator in this room, I destroyed the swivel chair, pressed the switch on the table, opened two secret rooms, and obtained the blue card and the destruction gun. Open the bank door with a blue card. Banks are full of institutions and dark passages. When entering the bank lobby, the three switches on the desk cooperate with the switch in front of the bulletin board to open the next door (if you set the switch on the bulletin board to 1, press the one on the left of the switch on the desk). After the door is opened, it enters the maze with four giant gear shafts and jumps on the platform in the middle of the gear, which can make the gear rotate and shuttle back and forth through the gear gap. You can get a red card and a jet pack by taking the elevator when you get in. Open the door of the safe room with a red card, which locks a group of monsters. After the fierce battle, the safe house was blasted, and there was a bottom inside.

The third blood area (flood area)

After sliding into the water from the cliff, you can see a room on the left side of the water, but you need to open the door with yellowcard. In addition, a dark tunnel can be blasted at the bottom of the rock on the right side of the water. After acquiring weapons, you can continue to dive until you see a small platform with a stream on it. After landing from here, take the mountain road and get the blue card. Go back to the water and open the blue door. You can get yellowcard after killing monsters.

Enter a room in the water, open the door with yellowcard and go up the stairs. Not only surfaced, but also came to another place. There is a jet pack in the secret room on the right side of the door. Return to the water from the yellow door, go down the stairs to the ground floor and open the underwater door. At this time, the secret room under the neon light is also opened, and you can get the red card.

After entering the red door, the words on the wooden box at the entrance are secret switches, and there is an enhanced alien in the wooden box. I accidentally fell into a deep well in the battle. Although he was not injured, he was suddenly attacked by an automatic laser gun when he surfaced. After destroying the monster, I passed the test.

On the fourth floor, the rumble of Los Angeles

Drop a remote-controlled bomb and kill several monsters. After going down, jump on the fence of the opposite tall building to get armor. The fence of the giant TV screen will collapse. After killing several pig-headed policemen, I entered a room and got a blue card. Blast the middle wall and come to a new place. Take the elevator on the left to the top floor. Fly to the opposite room with a jet pack. After getting the red card, press the switch next to the table, quickly run into the room on the right, open the door with the red card, reach the bottom, and leave by helicopter on the tarmac.

The fifth customs film factory (film set)

During the flight, the helicopter was hit by the monster's gunfire and fell to the ground. After the jumper landed, he cleaned up the scattered articles, then jumped on the fence, jumped to the edge of the giant billboard, and entered the back secret room at the place marked with a triangle. Go straight ahead after you come out, and a row of windows will automatically open on the wall. After killing the monster, jump in and open the secret room behind the fuel tank with the cash register. There is a blue card under the phone next to the fuel tank. After opening the blue gate, destroy many monsters. Go in through the ventilation pipes, which crisscross, and one of them can reach the film studio. Yellowcard, jet packs and some weapons can be obtained in the studio. There is a hidden switch on the signboard of the studio, which can be used to open the green background leading to the first secret level.

Go back to your room, open the yellow door and enter the space training room. You can get a red card and some items. After opening the red door, you can open the door to the bottom of this customs (in the room of the fuel tank).

Secret level, level down.

There are four different situations at this level. First, attack the cave guarded by the tiger-headed paratroopers and get the reducing gun. Then destroy the alien monsters in the brown cave. In the gray-white pavilion, destroy monsters such as alien generals, alien frisbees, pig-headed police officers and brain-sucking monsters, and obtain weapons and ammunition. Then climb up the dark hill in the magma pool, which is the bottom of this pass, and open the iron gate to fight the devil.
